Weir reported equations for estimating the basal metabolic rate. The author is from the University of Glasgow.
Parameters:
(1) liters of oxygen used per minute
(2) liters of CO2 produced per minute
total kcal per minute =
= (3.9 * (liters of oxygen)) + (1.1 * (liters of carbon dioxide))
REE in kcal per day =
= (total kcal per minute) * 1440
